MacBook Air
The MacBook Air is a line of notebook computers developed and manufactured by Apple Inc. It consists of a full-size keyboard, a machined aluminum case, and, in the more modern versions, a thin light structure.
The Air was originally positioned above the previous MacBook line as a premium ultraportable. Since then, the original MacBook's discontinuation in 2011, and lowered prices on subsequent iterations, have made the Air Apple's entry-level notebook. In the current product line, the MacBook Air is situated below the performance range MacBook Pro. The Intel-based MacBook Air was introduced in January 2008 with a 13.3-inch screen, and was promoted as the world's thinnest notebook, opening a laptop category known as the ultrabook family.
Apple released a second-generation MacBook Air in October 2010, with a redesigned tapered chassis, standard solid-state storage, and added a smaller 11.6-inch version. Later revisions added Intel Core i5 or i7 processors and Thunderbolt. The third generation was released in October 2018, with reduced dimensions, a Retina display, and combination USB-C/Thunderbolt 3 ports for data and power. An updated model was released in February 2020 with the Magic Keyboard and an option for an Intel Core i7 processor.
In November 2020, Apple released the first MacBook Air with Apple silicon based on the Apple M1 processor.
First generation
Steve Jobs introduced the MacBook Air during Apple’s keynote address at the 2008 Macworld conference on January 15, 2008. The first generation MacBook Air was a 13.3" model, initially promoted as the world's thinnest notebook at 1.9 cm (a previous record holder, 2005's Toshiba Portege R200, was 1.98 cm high). It featured a custom Intel Merom CPU and Intel GMA GPU which were 40% as big as the standard chip package. It also featured an anti-glare LED backlit display, a full-size keyboard, and a large trackpad that responded to multi-touch gestures such as pinching, swiping, and rotating.
The MacBook Air was the first subcompact notebook offered by Apple after the 12" PowerBook G4 discontinued in 2006. It was also Apple's first computer with an optional solid-state drive. It was Apple's first notebook since the PowerBook 2400c without a built-in removable media drive. To read optical disks, users could either purchase an external USB drive such as Apple's SuperDrive or use the bundled Remote Disc software to access the drive of another computer wirelessly that has the program installed. The MacBook Air also did without a FireWire port, Ethernet port, line-in, and a Kensington Security Slot.
On October 14, 2008, a new model was announced with a low-voltage Penryn processor and Nvidia GeForce graphics. Storage capacity was increased to a 128 GB SSD or a 120 GB HDD, and the micro-DVI video port was replaced by the Mini DisplayPort. A mid-2009 version featured slightly higher battery capacity and a faster Penryn CPU.
